Genuine BMW Loctite 5970 Chemical Sealant 83190404517

The Genuine BMW OEM Loctite 5970 Chemical Sealant (83190404517) is the factory-approved sealing solution used by BMW to seal differential covers and pan covers. In many modern BMW applications, traditional gaskets have been discontinued in favour of this high-performance chemical sealant, making Loctite 5970 an essential consumable when servicing or removing the differential cover.

Developed to meet BMW’s exact specifications, Loctite 5970 delivers excellent flexibility, strong adhesion, and an instant, reliable seal. It is specifically formulated to cope with the thermal expansion, vibration, and fluid exposure present in drivetrain components, ensuring a durable, leak-free seal once cured.

Whenever a differential cover is removed—whether for routine servicing, internal inspection, or component upgrades—this sealant is required to correctly reseal the cover to the differential housing and restore factory-level sealing integrity.

What This Sealant Is Used For

Loctite 5970 is applied directly to the mating surfaces of:

• Differential covers

• Differential pan covers

It replaces traditional gaskets by forming a flexible, uniform sealing layer that conforms to surface imperfections and maintains sealing performance under load and temperature changes.

Why BMW Uses Loctite 5970

BMW specifies Loctite 5970 in place of conventional gaskets to:

• Reduce the risk of differential oil leaks

Using the correct BMW-approved sealant is critical to maintaining drivetrain integrity and avoiding repeat labour due to leaks.

Why Choose Genuine BMW OEM Sealant?

Using the correct factory-approved sealant ensures proper curing, long-term durability, and compatibility with BMW differential housings—something generic sealants cannot always guarantee.
